[RESOLVED] htaccess

regevlio

Hey There

For some reason my mod_redirect is not working
even for a simple redirect such as

<IfModule mod_rewrite.c>
Options +FollowSymLinks
Options +Indexes
RewriteEngine On
RewriteBase /
RewriteRule index.php index.htm
</IfModule>

i get an error 500

why is that ?
my site is hosted with godaddy and according to them they enable mod rewrite by default

thanks

dagon

I would just offer this generic debugging advice - drop the <IfModule mod_rewrite.c> (and the close) and remove all the lines then add back one at a time till you find he culprit.

regevlio

i know that this is my problem RewriteRule index.php index.htm
but i don't understand why, it should work right ?

dagon

try adding

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

above the rule

regevlio

well

Although i didn't get an error this time
I'm not quite sure what to do next

i want to create friendly URL's
My links are like this : index.php?id=5&name=some_example

and i want them to look like : some_example.html

what rule will work for me ?

Derokorian

RewriteRule ^index.php$ index.htm

Try that line instead of your current line.

Derokorian

As far as your last post, that's not what you're doing at all with your current rule. This would rewrite some_example.html to index.php?name=some_example ;

RewriteRule ^([a-zA-Z_]+)\.html$ index.php?name=$1

However in order to get the id in there it will have to be present in the url somehow. For example 5-some_example.html to index.php?id=5&name=some_example:

RewriteRule ^([0-9]+)-([a-zA-Z_]+)\.html$ index.php?id=$1&name=$2

HTH

regevlio

thanks but its not working and its driving me nuts

here is what in my .htacces

<IfModule mod_rewrite.c>
Options +FollowSymLinks
Options -MultiViews
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^{([0-9]+)-([a-zA-Z_]+).html$} index.php?id=$1&name=$2
</IfModule>

nothing happens
Any ideas ?

Derokorian

What is the address you are trying to access to verify this doesn't work? Maybe start small, as others have stated and instead of trying to match patterns (as in my last example) you simply try to rewrite index.html to index.php when you get that working you can go add from there.

Derokorian

AKA I would put just this in my .htaccess to verify rewrite is working:

RewriteEngine On
RewriteBase /
RewriteRule ^index\.html$ index.php

Verify that just those three lines are working before you try to do more.

regevlio

yeah i did , tried an easy one like index.php index.html and that didn't work either
im working with godaddy hosting and they say that everything is installed correctly on their servers.

accessing index.html worked but when i accessed index.php the adress stayed the same - "index.php"

any other ideas ?

Derokorian

Mod_rewrite does not change the address in the address bar. The point of mod_rewrite is to change where that address points server side. Take these files put them in the root and see what I mean:

index.html

<html>
   <body>
      <h3>This is Index.html</h3>
   </body>
</html>

index.php

<html>
   <body>
<?php
   echo "This is the index.php page";
?>
   </body>
</html>

.htaccess

RewriteEngine On
RewriteBase /
RewriteRule ^index\.html$ index.php

Then try to access index.html in the address bar and see what displays.

Derokorian

FYI using those 3 files as is on my localhost (WAMP) my linux testing server and my godaddy server all produce "This is the index.php page" when i try to access index.html

Well of course not... neither does PHP or any other server-side concept since the "address bar" is on the client. 😉

Ignoring that detail, mod_rewrite certainly can cause a change in the address bar. If the 2nd value for RewriteRule is a full URI (ex. it begins with 'http(s)://') or you specify the 'R' flag, the rewrite will be handled as an HTTP redirect, meaning the server will tell the browser to re-request the content at some new location (which the browser will show in the address bar).

EDIT: To clarify the contrast, if neither of the above conditions are true, Apache handles the URL rewrite internally, e.g. it modifies the URL requested by the client and then continues its internal decision making processes to decide how it should reply to the original request.

regevlio

well that's understandable now.

What i don't understand is how it works on dynamic pages.

once i have made a rewrite rule how can the server know based on a request to www.mysite.com/some_name.html
to actually ask for www.mysite.com/index.php?id=1&name=some_name ?

Derokorian

Well you use regex to find a pattern and move that match to a different spot. However, given you example this wouldn't be entirely possible unless the id never changed. Otherwise how would it know when some_name.html is supposed to be with a certain id number. To get your exact example working you'd have to hardcode in id as 1.

RewriteEngine On
RewriteBase /
RewriteRule ^([a-zA-Z_-]+)\.html$ index.php?id=1&name=$1

In the first part of the rule the pattern you are matching is within parentheses () and then in the second part the $1 is a back reference to that match. If you had more than one pattern in parentheses you would the number following the dollar sign in part two would be a reference to the position of the pattern in the first part. Take this for example:
^{([0-9]+)([a-zA-Z]+).*$} index.php?first=$1&second=$2

This would take numbers at the front for the first match followed by letters for the second match with any remaining characters lost.

bradgrafelman

Based on that URL, you can't get the 'id=1' part. However, this rule:

RewriteRule ^([0-9]+)-([a-zA-Z_]+)\.html$ index.php?id=$1&name=$2

suggests that you should have URLs in the form of: [noparse]www.mysite.com/123-some_name.html[/noparse] in order for them to be rewritten to [noparse]www.mysite.com/index.php?id=123&name=some_name[/noparse]

EDIT: Woops.. didn't see the second page before replying.

thanks ...

Got the trick and also got it working.
You have been extremely helpful i now finally after 3 days will go to sleep tonight :-)

Thanks again
